I need a case a good child proof case. Would love something waterproof, but I'm not looking to spend over $50. Been looking at the griffin survivor mostly after seeing reviews of the two compared on youtube, however I want to know is there a major difference? Ive heard so far that the otterbox is better and not as bulky. In a nutshell I need a case that can handle a fall from a table to the floor, it doesn't need to be those two brands as long as it will keep the ipad protected since my two year old uses the ipad Thanks in advance.
